Karthik,
Even though VEX-U is allowed to do creative things with their motors, for VRC there is very strict R15:
However, a couple of years back you ruled that it is legal to use internal gears, sold in refub kits, outside of the motor for any purpose and presumably with any modification, but it would be not be legal to use any other motor parts outside of the motor.
Could you confirm that this ruling still stands, or it would be possible to repurpose in VRC other mechanical motor parts as well?
Thanks
